    I used an OBDII reader to read out the code from my 96 SL2(90K
    mileages). It is 0133 (CO2 Sensor) and 0304 (4th Cylinder Misfire).

    Are these serious issue? If it only affects engine performance, I don't
    want to spend any extra effort on this car.

    Thx.

    the o2 sensor will definetly screw with your milage BUT I would fix the
    misfire first and see iff the other goes away for the sensor is up
    there in bucks.. there are 2 also I believe.
    The misfire could be plug or plug wire probably plug wires.. I would
    replace the plug wires and do it right with the conductive grease and
    all then replace the plugs if it hasn't been tuned for awhile.

    Is it hard to replace the plug wire DIY? I find can buy it from ebay
    around $30 (incl shipping).

    Or, I can just get it done with an engine tune up service?

    it's a breese.. just replace one at a time so you don't mess us the
    order.. plug wires for a saturn are $24 at autozone or carquest or
    advance auto parts.

    Clean off the ignition coil tower at the same time. It gets corroded over
    time and can affect performance. Also replace the plugs and gap them
    properly (0.040") at the same time. The complete job shouldn't take more
    than 30 minutes tops. Also make sure you route the plug wires the exact
    same way as the originals. Good reason to do them one at a time as
    suggested.
